 What are the appropriate degrees of freedom for describing fission of heavy nuclei (171 ≤ A ≤ 330)?  Fission barrier heights for 5239 nuclides between the proton and neutron drip lines were calculated using the following set of only 5 parameters:  Elongation  Neck diameter  Left-fragment spheroidal deformation  Right-fragment spheroidal deformation  Nascent fragment mass asymmetry P.

 A brute-force achievement for modern computing and nuclear theory  Over 5,000,000 different shape configurations were considered, without conventional minimization techniques  Where experimental data is known, theory agrees with experiment to within about 1 MeV Z.
